What is radiation?

Radiation is the emission of energy from any source, which travels through space and may be absorbed by objects.

What are the types of radiation?

The main types of radiation are alpha radiation, beta radiation, gamma radiation, and electromagnetic radiation.

What is alpha radiation?

Alpha radiation consists of alpha particles, which are made up of two protons and two neutrons, and is generally emitted by heavy elements.

What is beta radiation?

Beta radiation consists of beta particles, which are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei.

What is gamma radiation?

Gamma radiation is a type of electromagnetic radiation arising from the radioactive decay of atomic nuclei and is highly penetrative.

What is electromagnetic radiation?

Electromagnetic radiation is a form of energy that travels through space and can take the form of waves, including visible light, radio waves, and X-rays.
